I sent a Private Message, but it is not in my Outbox

[Timothy]

There seems to be a glitch in the Private Message feature which causes a PM to fail to be posted in the Sender's Outbox when the person previews the message before sending it. This problem will be resolved when the next software upgrade takes place, which may be fairly soon (watch the Announcements section for notification of when this will take place).

In the meantime, except for a few occasions when the forum software hiccups, all PMs are sent just fine, even though they fail to post in your Outbox.
